Specification of Letters Patent.

Application filed August 16, 1917. Serial No, 186,457.

fore, resides in a structure of block dropper which is yieldingly supported in position so that in case of improper manipulation, the block dropper will yield rearwardly to avoid all breakage. "In this connection, my

block dropper is preferably movable froma lowered position to an elevated position or from an operative to an inoperative, with the supporting structure so arranged and mounted to permit its rearward yielding movement'under abnormal conditions.

Another object of my invention also re sides in the combination with a block dropper movable from a lower to an'upper' position,of a peculiar ty'pefof placer clip designed to n ormally engage the top edge of a block, but 'which is so formed along its outer face portion to prevent it from engaging the transverse slots in the block itself i1 sheuld' this latter not be inproper position meral 1.

at the time the feeder head descends.

The preferred embodiment of my inven-v tion is shown in the accompanying sheet of drawings, n which similar characters of reference designate corresponding parts,

and in which: I

Figure 1 is a view in perspective of a baling press with the parts broken away showingmy improved type of block droper, p Fig. 2 is a View in perspective of my improved block dropper shown detached and shown in loweredposition, and, n

Fig. 3 is a fragmentary perspective of a portion of the feeder head and block dropper.

designated generally by the reference nu- A plunger or headblock 2 is designed to reciprocate back and forth within the bale chamber 3 in the customary manner and the feeder head 1 is designed to move up and down by means of its acturelates to baling presses In Fig. 1, the body of the baling press is Patented Apr. e, 1918.

the reference numeral 5. Onthe top of the rear portion of the press,- I mount a plate 6 whichforms the support for the block dropper itself. This blockdroppe'r comprises a rectangularly shaped holder member '7 provided with a pair of spring clips 8 at its lower forward portion to frictionally hold the block 9 in position until the latter is engaged by'the placer clip 10 carried by the feeder head 4. The holder member 7 is provided with a pair of downwardly extending legs 11 which are pivotally mounted to the cross rod shown at 12. Y This latter is slidablymounted within the slots 13 of the supporting clips shown at ltwhich supporting clips extend rearwardly and are then bent at right angles, as shown at 15. The ends of the pivot rod 12 project through the slots 13 and these slots are of suflicient length to permit the proper rearward movement of the block dropper under abnormal conditions, as will be presently related. A-pair of bolts 16 extend longitudinally of each of the frame pieces 14 and are provided with'a clevis head 17 at their forward ends. These clevis heads are made to embrace the legs 11 and also engage the cross rod 12 as shown. The bolts themselves project rearwardly through the inturned ends 15 of the frame pieces 14 and springs 18 encircle these bolts between their two points of support.

A big difficulty in the use of these baling presses has been found to be the scarcity of skilled help to properly manipulate the block dropper. A frequent faulty opera. tion is one wherein the block dropper is not moved to its extreme upright position as the feeder head descends, with the result thatthe placer clip 10 engage the front face of: the block to cause a jam, with the result that either the feeder head or the block dropper has to break. 'In my conunder these conditions and the result is that the entire block support structure moves rea'rwardly springs 18.

To prevent the placer cliplO from obtaining a firm grip in one of the transverse against the tension of the new,

slots 19 formed in the blocks 9, I have pro vided a clip wherein the bottom portion :20 is substantially flat to engage the top edge 21 of the blocks and an upstanding face 22 also ubstantially flat with a rounded corner 23 between these two portions. lhis fiat face 22 is preferably inclined to bring the corner 23 away from the block 9 when the feeder head is near the end. of its stroke as may be deduced from the showing in Fig. l, to absolutely prevent it catching in any of the slots 19 should the block not have been properly elevated. It will be understood that it is necessary to provide the blocks 9 with the slots 19 in order to facilitate the manipulation of the binding wires. in case the block is in only a partially elevated position, the rounded corner 23 cannot engage any of the small slots 19 because of its curvature and thus there is presented a rolling action out of the slots as the feeder head descends, and the flat front face :22 finally lies parallel with the front face of the block and then in an inclined relation therewith and in this manner the entire block supporting structure is pushed rearwardly against the tension of the springs 18.

What 1 claim, is:

1. In a baling press, the combination with a feeder head, of a block dropper comprising a holder member pivotally supported on the press to swing between a lower and an upper position into or out of the path ofmovement of said feeder head, and means for permitting said pivotal connection a yielding movement away from said feeder head under abnormal conditions.

2. In a baling press, the combination with a feeder head, of a blocl: dropper comprising a holder member, means for pivotally supporting said holder upon the press to swing between a lower and an upper position into or out of the path of movement of said feeder head, and means for yieldingly holding said pivot support in normal posi-- tion but permitting" its rearward movement under abnormal conditions.

3. In a baling press, the combination with a feeder head, of a block dropper comprising a holder member, a transverse rod upon 'which said holder is pivotally mounted,

means for supporting said rod to permit it an appreciable rearward movement, and spring means normally holding said rod in its forward position.

d. In a baling press, the combination with a feeder head, of a block dropper comprising a holder member, a pair of downwardly projecting legs on said member, a pair of slotted clips carried by the press, a rod supported in said slots to which said legs are pivoted, a pair of rcarwardly extending bolts secured to said rod at their front ends to slide over the face of the block under ab-' normal conditions.

6. in a baling press, the combination with a feeder head, of a block dropper comprising a holder member supported on said press to swing from a lower to an upper position and supported to yield rearwardly under abnormal conditions, and a placer clip on said feeder head formed with a substantially flat bottom for engagiu the end of the block and a substantially flat front side at substantially 'ight armies to the bottom but formed with a rounded corner portion between said bottom and side.

7. In a baling press, the combination with a feeder-head, of a block dropper comprising a holder member mounted to move be tween an operative and an inoperative position into or out of the path of movement of said feeder head, and means for permit ting said member a yielding movement away from said feeder head under abnormal condi tions.

8. In a baling press the combination with a feeder head of a block dropper comprising a holder member mounted to move between an operative and an inoperative position into or out of the path of. movementof said feeder head, means for permitting said member a yielding movement away from. said feeder head under abnormal conditions, and a placer clip on said feeder head adapted to disengage itself from the grooves in the block during the descent of said feeder head under abnormal conditions.

9. In a baling press, the combination with 'eeder head member of a block dropper member mounted on the press to move between an operative and an inoperative position into or out of the path of movement of said feeder head, and means for permitting one of said members a yielding movement away from the other a su'liicient distance to permit them to pass each other under abnormal conditions and on the descent of said feeder head member.

in testimony whereof I aiiix my signature in presence of two witnesses.
